Geometrical representation of a monochromatic electromagnetic wave using the tangential vector approach

Abstract

The aim of this work is to develop a coherent polarimetric model and to find a geometrical description of a monochromatic wave. The spinor form of the electrical field, its links to the coherency matrix and the Poincare` sphere are introduced with the aim to obtain a geometrical representation of the spinor. It consists, from the ``polarization point of view``, on the polarization vector and a tangential plane to the Poincare` sphere where it is possible to visualize the zero phase.
